Objectives: The Imperial County's Asthma CER project is a family-clinic-community intervention designed to improve asthma control. The objectives of this study are to determine whether this combined approach (family clinic-community) is more effective at promoting asthma control, quality of life and improved lung functioning than a family-community intervention, a clinic-community intervention, or a community only intervention. The ultimate goal is to identify feasible and effective methods for promoting lifelong asthma control.
